• Raymarine Airmar ST800 Speed/Temp Transducer

Part number 31-487-1-02

The ST800 is Airmar's standard, thru-hull speed sensor. Digital signal processing inside the housing provides speed and temperature data to a chart plotter, radar screen, or digital display in analog format. The plastic P120 and bronze B120 housing options are available to meet most hull requirements. These low-profile units are nearly flush and minimize drag with only 5 mm (3/16") extending outside of the hull.
